Title: Oxygen concentration detector
Inventor: ASAKURA MASAHIKO
IPC: G01N27/27
Filed: 1986-03-19
Abstract: PURPOSE:To prevent a possible blackening phenomenon, by reducing a supply current between electrodes of an oxygen pump element after the voltage generated between electrodes of a battery element controlled to a constant voltage reaches a fixed value and then, a specified time elapses. CONSTITUTION:A current is supplied to between electrodes 5 and 6 of an oxygen pump element 1 from a current supply circuit 11. An output voltage Vs' of a non-inversion amplifier 30 goes up with a rise in a voltage Vs between electrode plates 7 and 8 of a battery element 2. When the voltage Vs' rises sharply, an output voltage of an integrating circuit 50 of a limiter circuit 40 goes up gradually. A transistor 48 is turned ON after the voltage Vs exceeds a specified value and a delay time elapses to make the base potential of a transistor 13 almost equal to to the earth potential, which turns OFF the transistor 13 to reduce a pump current. Thus, as the voltage Vs' reaches a value approaching a range of causing a blackening phenomenon, the pump current is reduced immediately before it attains the area of causing a blackening phenomenon after a delay time.

Abstract: PURPOSE:To obtain the large effective area of filtration, by not forming a low temperature range caused from uneven heating to an inlet face of a filter material in a filter but preventing blocking of the filter material due to an unburned seized fine particle. CONSTITUTION:If a selector valve 21 and closing valve 22 are closed, exhaust bypasses a filter 13 to reach a bypass passage 19 to flow out to the atmosphere. Air from an air supplier flows in through the filter 13 from an air inflow port 24 in the downstream side of the filter 13 toward an air outflow port 23 in the upstream side. If a filter material 12 heated by a heating means 16 reaches prescribed temperature, seized fine particles are ignited to propagate combustion toward an inlet face from an outlet face 15. Here an unburned part is generated in a part in which the means 16 of the face 15 is positioned, however, a fine particle seized to the inlet face not generating a low temperature range is perfectly burned.

Title: Method for refining metallic gallium
Inventor: IOKA MASAYOSHI
IPC: C22B58/00
Filed: 1989-03-17
Abstract: PURPOSE:To obtain high purity Ga crystals with high refining efficiency, at the time of crystallizing a Ga molten metal by pulling Ga crystals upward while they are rotated, by forming an acid soln. layer on the surface of the Ga molten metal. CONSTITUTION:At the time of crystallizing a crude Ga molten metal, e.g., recovered from scrap by a rotation upward pulling method, the surface of the Ga molten metal existing as a mother liquor is coated with an acid soln. layer. As the acid soln., the water soln. contg. strong acid such as hydrochloric acid, sulfuric acid, perchloric acid and formic acid is preferably used. Furthermore, the acid concn. of the acid soln. is generally regulated to the range of 0.05 to 5 N, preferably 0.1 to 1 N. Then, the acid soln. is brought into contact with the Ga molten metal as a mother liquor, by which impurity metals included in the Ga molten metal are melted away into the acid soln. Simultaneously, the impurity metals are oxidized by dissolved oxygen in the acid soln. and are precipitated as a solid matter. As the result, the sticking of Ga microcrystals including impurity metals into the surface of a crystal bar to be pulled up is prevented, by which high purity metallic Ga can be pulled up.

IPC: G06F13/38
Filed: 1991-03-06
Abstract: PURPOSE:To prevent the malfunctions owing to the output simultaneous operating noises by controlling the enable timing of a 3-state output buffer. CONSTITUTION:An output buffer group 10 is always kept in a normal output state. An enable control signal has such a waveform that sets the outputs of all 3-state buffers in a high impedance state at the first of each cycle and then sets an output buffer group 20 in a normal output state after a prescribed time when the internal operation of an LSI is complete. This control signal is inputted to an input terminal 1 synchronously with a test pattern cycle. The delay circuits 3 and 6 delay the enable signal by a time enough for each output buffer to work and controls successively the output buffers to the normal output state from the high impedance state so that the operations of the output buffer groups 20, 30 and 40 never overlap with each other. As a result, all outputs are divided into plural groups and these groups of outputs work one by one when the LSI is tested in a single unit. Thus the noises caused by the simultaneous operations are reduced and the malfunctions owing to these noises can be prevented.

Title: Pressure-sensitive resistance change type conductive composition
Inventor: YASUDA MASAO
IPC: H01C10/10
Filed: 1998-02-28
Abstract: PROBLEM TO BE SOLVED: To reduce the cost, and adjust the rate of change of resistance value arbitrarily and easily, by using a liquid rubber for a matrix rubber and mixing carbon particles and a very small quantity of highresistance particles. SOLUTION: A liquid silicone rubber is used for a matrix in which conductive particles and high-resistance particles are to be kneaded. Approximately 50-200 pts.wt. of carbon particles having an average grain size of approximately 2-50 μm and approximately 0.1-5 pts.wt. of high-resistance particles having a specific electric resistance of approximately 10-200 Ωcm when pressurized at 4.9×10<5> Pa (5 kg/cm<2> ) and having an average grain size of approximately 0.05-5 mm are kneaded into the matrix, thus producing a pressure-sensitive conductive composition. In this case, titanium oxide particles or the like, or particles with their surfaces coated with titanium oxide or the like, are used as the high- resistance particles. By changing the quantity of high-resistance particles to be mixed, the rate of change of resistance value is varied from 10<1> to 10<5> or more.  Thus, the rate of change of resistance value is made arbitrarily and easily adjustable and the cost is reduced.

Title: Method for improving fatique strength of welded high tensile steel
Inventor: KURAUSU HOTSUFUMAN
IPC: B23K9/23
Filed: 1989-03-17
Abstract: PURPOSE: To improve the fatigue strength of a weld joint transition part to that of a base metal to be welded, by heating the weld joint transition part in a weld zone where high tensile steels are butt-welded to each other by supplying a prescribed local thermal energy.  
     CONSTITUTION: When high tensile steels of 14-16mm in thickness are butt-welded, the fatigue strength is improved to prevent generation of the fatigue breakage at a transition part of the weld joint to a base metal. Thus, the transition part of the seam weld joint to the high tensile base metal free from any heat effect by welding is heated to the saturated preheat temperature where the fatigue strength of the weld joint is approximately same as that of the base metal in a method of the inert gas arc welding using a W electrode or irradiation of the laser beam. In the case of the high interval energy under the supply of the local energy by the above-mentioned means, heating is made at the low saturated preheat temperature, while in the low interval energy, heating is made at the high saturated preheat temperature. The fatigue strength of the transition part of the weld joint to the base metal can be improved to that of the base metal.
